Leviticus 23:6-8

MSTC^{(i) 6} And the fifteenth day of the same month is the feast of sweet bread unto the LORD; seven days ye must eat unleavened bread. ⁷ The first day shall be a holy feast unto you, so that ye may do no laborious work therein. ⁸ But ye shall offer sacrifices unto the LORD seven days, and the seventh day also shall be a holy feast, so that ye may do no laborious work therein.'"
